Vinegar is an extremely acidic liquid. Very few microorganisms (ie bacteria and fungus which cause foods to spoil) can survive in such an acidic environment. Among other effects, it can destroy their cell walls, and prevent their own enzymes working (enzymes are extremely pH sensitive). There are a small number of microorgamisms which are adapted to survive in extreme acidity. However, this adaptation prevents them from surviving in more 'normal' environments. Therefore, anything which can survive in the vinegar, will not likely survive on your kitchen surface, and the same is true the other way around. Therefore, as vitually nothing can colonise whatever is in the vinegar, the food will be very effectively preserved. . . . . . . . . . . you can say........................ . . the low pH a nd high acidity of vinegar destroy bacteria

Answer:
DNA
Explanation:
Deoxyribonucleic acid (DNA) is known as the hereditary material of cells. It carries information for coding all type of proteins in the body.
As helicases are proteins, the genetic code from which they are to be made would be present in a specific sequence on part of DNA. This code would be transcribed and mRNA will be formed. After this, the mRNA will be translated and modified into a helicase enzyme.
Answer:
For any experiment we can say that light waves are the electromagnetic waves because they make up what is known as the electromagnetic spectrum.
Explanation:
- Light is the moving energy form that is made up of tiny particles known as photons.
- The light waves comprises of both magnetic and electric aspects hence known as electromagnetic.
- The process of propagation of light wave is : the fields vibrates perpendicularly in the same direction of propagation of the wave, and at 90 degree angle with each other.
- Similar to sound waves, light wave can interfere with each other.
